"There are always lessons to be learnt, and I will do my utmost to support, value and uplift women of colour working in politics, particularly those with whom I share common ground."

Ms Lucas added: "There are profound policy disagreements between many of the women I wrote to, and I will continue to challenge views that do not align with my values no matter the working relationship.

"But we are united in our belief that a no-deal Brexit would be disastrous for this country, and needs to be prevented."

'We are going to leave the EU on 31 October'

Britain is on course for Brexit to happen on 31 October, after Boris Johnson became prime minister on the back of his pledge to ensure it happens on Halloween, "do or die".

The government has demanded Brussels renegotiate the current withdrawal agreement secured by Theresa May after it was defeated three times in parliament, but the EU has refused.

Some MPs are plotting how to block the no-deal default in less than 90 days' time by calling a no-confidence vote in Mr Johnson, which if he lost could trigger a general election.
